The FX Crown I have bought has a new power dial that reads 1,3,5,7 up to 23. That is not described in the manual that came with the rifle nor can I find reference to it anywhere on the web. The number 13 is circled, is that the recommended setting and does anyone have any idea what the other settings mean? Also, what scope mounts do you use? I have tried Hawke and Wulf all described as "high" but none allow the mag to install clear of the scope (MTC King Cobra). Also, on the last shot if I have the rifle pointed down the pellet falls part way out of the mag and jams the action. Is that just something to be aware of and manage? Also, something moves and rattles inside the action when the rifle is uncocked. Again, is this something to be aware of but does not mean an item is loose in the rifle?
